摘要
We report a comparative study of the L3-M45M45 Auger spectra of Cu, Cu2O and CuO. The large intensity of the uncorrelated two-hole band-like spectrum in the L3-M45M45 Auger spectra of Cu2O and CuO and the spectral shapes for these transitions indicate strong Cu 3d-O 2p hybridization in the oxides. The L2-L3M45 CK rates obtained for these compounds indicate the stability of the Cu 3d level with increasing oxidation state of Cu. We also provide a quantitative estimate of the contributions of the different processes that lead to the formation of the L3-M45M45 Auger satellite in Cu, Cu2O and CuO.
